Galt gunman's stepfather reacts to deadly shooting

For the stepfather of deceased 30-year-old Humphrey Gascon, reality is still sinking in.

"I just found out about it earlier today," he told KCRA 3 on Wednesday.

Gascon is accused of killing Officer Kevin Tonn, 35, on Tuesday -- and then turning the gun on himself.

But, the stepfather said, what happened leading up to the tragedy isn't something he would know anything about.

"I haven't seen him in about a year," he said.

So, who was Humphrey Gascon?

Neighbors said he grew up in Stockton.

The Galt Police Department said he lived in Sacramento, then recently moved to Galt, where he was staying with family.

Gascon hasn't received more than a traffic citation from Stockton police, the department said.

But in 2001, the San Joaquin County Sheriff's Department charged him with the possession of a deadly weapon, specifically, a club.

"He was not a documented gang member, but a search of his residence did indicate he probably did have (a) gang affiliation," Galt police said. "But he was not documented -- but there was indication in his room and on his property that he was gang affiliated."

A former neighbor who knew Gascon said he seemed like a normal guy.

"I'm shocked -- because who would ever think?" Christine Jones said. "I can't believe why he would do such a thing, you know? It's hard to believe."

And for others, sadness and confusion surround the man police say took his own life, as well as the life of Officer Tonn.
